Abstract
We describe a pretreatment method before determining the total fluoride in solutions containing tetrafluoroborate ion (BF(4)(-)) with ion-selective electrodes (ISEs). BF(4)(-) was quantitatively converted to free fluoride by reacting with aluminum ions. The total fluoride concentration was then determined by ISE analysis without preliminary steam distillation using a tartrate- and tris(hydroxymethyl)methylamine (TRIS)-based total ionic strength adjustment buffer (TISAB). We investigated the effects of various factors on the decomposition of BF(4)(-) with aluminum ions, including the concentration of aluminum, pH, reaction temperature, and reaction time. The quantitative decomposition of BF(4)(-) was complete after 2 h at 50 degrees C or 1 h at 70 degrees C.
